ELECTRIC-LIQ HT ATTACHMENT.

SPECIFICATION forming part of Letters Patent No. 571,248, dated November10, 1896.

Application filed April 30, 1896.

To all whom t may con/cern:

Be it known that I, Josnrn 1I. RUsBv, a citizen of the United States,residing at Nutley, in the county of Essex and State of New Jersey, haveinvented new and useful Im provements in Electric-Light Attachments, ofwhich the following is a specification.

-The object of this invention is to provide a new and improved insulatorattachment for suspending an electric lamp from a ceiling or wall. V

To accomplish this object, my invention consists in the features ofconstruction and in the combination or arrangement of deviceshereinafter described and claimed, reference being made to theaccompanying drawings, in which- Figure 1 is an elevation of aninsulator sectioned along x x, Fig. 2. Fig. 2 is a section along y y,Fig. 1. Fig. 3 is a section along z z, Fig. 1. Fig. 4 is a section along'zu w, Fig. 3. Fig. 5 is a detail plan view of an insulator-section.Fig. 6 is a section along v fu, Fig. 4.

At certain places-as, for example, from a ceiling 1, Figs. 1 and 4--arefound projecting at times the screwthreaded ends 2 of gaspipes. If inplace of a chandelier or gas-nxture it is desired to connect an electriclamp to such pipe end 2, this result can be rapidly, effectively, andneatly accomplished by the following means: An insulator of porcelain orother suitable material has its sections 3 4 adapted to be connected anddisconnected, as presently explained. This insulator can be made in formof a rosette or any suitable or ornamental shape. The insulator-section3 is perforated, as at 5, for the passage of con` ductors or of cord 67. The section4has the passage 8 for the passage of conductors 9 10,which can be formed into a lamp-cord 11 for the suspension or connectionof a lamp, as

known. To the section 3, bysuitable fastening or screws 12, is connecteda crosspiece or support 13, having an upwardly-projecting socket 14,internally threaded to screw upon the screw-threaded end of the pipe 2,or, if desired, to a suitable extension-piece, (not shown,) which can bescrewed or inserted between the pipe 2 and cap 14 if it is desired toset the insulator at some distance from the pipe 2 or ceiling 1. Thesocket 14 when -screwed to pipe 2 will close the latter to pren ventescape of gas. The efficiency of closure 14 can be assured by a suitablewasher or packing 15, Fig. 1.

Secured to section 3 by screws or fastenings 16 are metallic orconducting strips or tongues bent, as shown at 17 18, Fig. 4, so thateach part 17 is engaged by fastenings 16, while part 18 is raised orheld a certain distance from section 3. Secured to section 4 by screwsor fastenings 19 are conductingstrips 2O 21, the strip parts 2O beingengaged by the fastenings 19, Fig. 6, while the parts 21 form hooks orfastenings. By placing the sections 3 4 together and giving a twist orturn to carry the hook parts 21 into engagement with tongue parts 18 thesections 3 4 are connected. A reverse movement enables the section 4 tobe readily disconnected from section 3.

The connections or contacts 17 13 and 20 21 form terminals for the cordsor conductors 6, 7, 9, and 10, and when the connections are inengagement to secure the section 4 to section 3 such engagement willclose the circuit or establish electrical contact as from a lead 6 tolead 9 and from a return 10 to a return 7. Springs .22, Fig. 4, suitablyplaced in seats or recesses in section 3 and made to act on contactparts 21 for holding the latter to contact parts 18, will secure aclosed circuit. The contact parts 18 and 21,` besides closing thecircuit, serve to connect the section 4 to section 3. As the section 4with its lamp or cord 11 can be readily detached or removed cords 11with their lamps can be readily dismounted or replaced, as required.

Instead of connecting the conductors 9 and directly to the terminals 2021 safety-fuses 9 and 10', Fig. 5, can be extended from said terminalsto binding posts or screws 23, con-- tacting with conducting-plates 24,having binding posts or screws 25, from which latter extend theconductors 9 10, forming cord 11.

By slipping a shell or tubing (not shown) over or about the socket 14and having such tubing of sufficient diameter and length to inclose thesocket 14 and pipe end 2, as also the wires 6 7, such wires will beconcealed and a neat finish will be given to the arrangement.

*What I claim as new, and desire to secure by Letters Patent, ish

ICO

l. An electric-lamp suspending attachment, consisting of aninsulator-section 3, provided with a central opening 5 for the passageof the electric conductors, and with hook-shaped contacts 18 to whichthe said conductors are connected, an insulator-section 4, provided witha central conductor-passage S, and with hoolcshaped contacts 21 to hookinto engagement with the hook-shaped contacts of the otherinsulator-section, and springs 22 acting upon the hook-shaped contactsof one section to press the saine against the hook-shaped contacts ofthe other section, substantially as described.
